Canopy Rentals?

So I will be attending Coachella Weekend 2 this year and having never been before, I'm trying to get my head around everything. I recently got a tent but after doing some research I found that a canopy may be necessary to escape from the heat. I would preferably like to rent one but does anyone know where I could do that or perhaps know of a cheaper alternative to buying a new one? I'm in the Los Angeles area and I have called a couple of camping stores that do rentals but none seem to do canopy rentals.
